Supply Lens automates the Fourth Hospitality supplier document cycle. Purchase orders in, order confirmations, despatch advices, invoices and credit notes out, mapped to your ERP or IMS with the right site codes, supplier IDs and Fourth tolerance rules built in.
Fourth's flow looks straightforward on paper. The work is in the site codes across a multi-brand estate, the confirmation each order expects back, the tolerance rules on every invoice and the despatch advice timing. Get any of it wrong and you eat a deduction. Supply Lens is configured for those rules out of the box.
Fourth receives supplier documents through a direct connection. Supply Lens manages the certificates, the partner profile and the gateway on your behalf, so you have no gateway of your own to build, run or maintain.
Fourth is a procurement platform rather than a single retailer, so orders arrive from operators running very different estates, from health clubs like David Lloyd through to restaurant and hotel groups. Each brand has its own sites, delivery windows and account structure. Supply Lens resolves the operator and the site before the order reaches your ERP, so multi-brand business does not have to be untangled afterwards.
Fourth identifies products by GS1 EAN and an internal product reference. Supply Lens maintains a cross-reference table mapping both to your own item codes, so the order lands correctly in your ERP regardless of which identifier Fourth sends.
Fourth applies strict invoice matching on price and quantity. Supply Lens validates the invoice against the originating purchase order and your agreed cost list before transmission, flagging any discrepancy for review rather than sending it and risking a deduction later.
Hospitality operators order to individual sites, not to a central depot, so a single supplier can be delivering to hundreds of addresses. Supply Lens maps every active site to the correct routing in your warehouse system, so each order lands against the right destination in your ERP without manual intervention.
Fourth expect a confirmation back before an order is treated as accepted, including any lines you cannot supply and the delivery date you are committing to. Supply Lens raises that confirmation from your ERP automatically, so sites know what is coming and when, and you are not fielding calls asking whether the order was received.
Supply Lens handles the full Fourth document set inbound and outbound, so documents are produced and transmitted automatically, without manual rekeying.
Supply Lens holds Fourth's rules and the connection itself so you don't have to. Your team provides credentials, product mappings and the agreed cost list. Everything else lives in the Supply Lens layer.
Your Fourth supplier code, GLN and trading partner profile registered with Fourth's gateway. Supply Lens manages the connection identifiers and certificates, so there is no setup needed your side.
Fourth EANs and product references mapped to your item codes. Pack-size variants, promotional lines and multi-pack SKUs are handled automatically once their cross-reference is established.
Each Fourth operator and site mapped to the matching customer account and delivery address in your ERP, so multi-brand orders route cleanly to the right destination on receipt.
Your agreed Fourth cost list registered for invoice validation. Tolerance rules applied per supplier agreement, and credit notes matched to the invoice they correct, so discrepancies surface your side first.
Supply Lens handles the scenarios that typically cause invoice rejections, deductions or document mismatches in the Fourth flow.
The format never reaches your system. Supply Lens turns Fourth's purchase order into a clean payload your ERP already understands and renders every outbound document in the structure Fourth requires on the way back out. Your team works in their normal interface, the format conversion happens in the Supply Lens layer.
Invoice values are validated against the originating purchase order and your agreed Fourth cost list before submission. Discrepancies are flagged before the invoice is sent, giving your team a chance to correct or query rather than receive a Fourth deduction weeks later.
The confirmation goes back automatically as soon as the order is accepted in your ERP, with any short-supplied lines and the committed delivery date on it. Sites see the answer in Fourth rather than phoning to ask, and the despatch advice follows the same route when the goods leave.
Unrecognised EANs go to an exception queue immediately. The order is held, your team is notified with the full Fourth context, the mapping is added and the order is re-triggered. No silent drop, no late invoice, no missed delivery window.
Fourth onboarding involves their supplier team, the connection setup and your internal product and pricing data. Supply Lens manages the configuration, the gateway and the format conversion. You provide the inputs.
